New polyurethane prepolymers for….
These prepolymers show a very low water uptake, which makes them suitable for the paper industry.
Low-acidity aromatic isocyanates and PU prepolymers.
Another series of prepolymers based on PPDI has also been developed recently.
D and technical service role developing IF and conventional prepolymers, Caytur and Adiprene K systems.
These prepolymers have inherently good industrial hygiene, as there is no free isocyanate due to the blocking.
Even when so-called low-free TDI prepolymers are used prepolymers with a free TDI content of.
Effective May 1, 2017, Covestro will raise the selling prices forits Desmodur and Baytec elastomer systems, which include prepolymers, polyols and curatives, by.
The focus is on our broad range of prepolymers with very low free isocyanate content.
The application range goes from classic transfer and metering tasks in the chemical and pharmaceutical industries up to the conveyance of monomers,oligomers and prepolymers during the production of polymers.
When producing aromatic isocyanate prepolymers it is important that the overall reaction mixture is slightly acidic.
Thanks to its experience and continuous technological innovations, we are able to provide coloured pastes, dispersions, varnishes,inks and customisable prepolymers according to the client's specific directions and reformulations.
However these monomers, oligomers or prepolymers mostly have health and procedural aspects, that need to be taken into account.
Compared to other manufacturers,LANXESS Urethane Systems has one of the broadest portfolios of prepolymers with low free isocyanate content for cast elastomers.
New Adiprene K blocked prepolymers are available with curing agents to make customer-specific, fully-formulated reactive systems.
It was this situation that prompted Bayer MaterialScience to develop prepolymers that are completely free of TDI, but which can be stored, processed and crosslinked in the same way as TDI prepolymers.
The LF TDI technology provided prepolymers with better dynamic properties, lower viscosities and longer pot life than the conventional prepolymers.
In addition to the standard TDI-based prepolymers a new TDI system made from bio-based polyols has been developed, named the Adilithe 9R series.
GAE GAE cross-links the prepolymers of polyurethane/acrylic hybrid dispersions via its free hydroxyl groups and via its polymerizable double bond.
Table 3 shows the resulting TDI prepolymers based on PTriMEG and PTMEG which when cured with MBOCA would give Shore hardnesses of 83A, 95A and 73D. Hardness.
Current tests have shown that elastomers based on prepolymers from the Baytec® MAX series of products also score excellent results when it comes to the key property of abrasion resistance.
The emergence of Suprasec 2154 prepolymer changes all that.
In particular, the PTriMEG based prepolymer at a 3.3% NCO had nearly half the viscosity of its PTMEG counterpart.
Polyurethane prepolymer is a thickener that can also be found in flexible foam products like packaging or insulation materials.
The MBOCA was melted at 1150C. The TDI/PTMEG prepolymer was mixed with MBOCA using a speed mixer at 2500 rpm for 30 seconds.
Suprasec 2154 prepolymer is based on Huntsman's proven Suprasec 2054 prepolymer chemistry, which is known for delivering consistent, high quality results.
Used on the isocyanate or'A' side of polyurea, Suprasec 2154 prepolymer has built in flame retardant features.
The following example is based on the stripping of Isocyanates from Prepolymer down to a final content of less than 0.1.
This is an isocyanate containing prepolymer(precursor) that reacts with water in the air and from the substrate when the carbon dioxide(CO2) is split off and becomes PU.
